Then either your connect call is wrong, or the process you're starting
doesn't flush its buffers properly.

With that code you won't ever get the output as soon as the process
produces it because you're waiting for the process to finish its execution
before anything happens. waitForFinish is a blocking method.

The only way to achieve what you want is using the readyRead signals and
making sure the process you start properly flushes its buffers.
